vTo WHoM VIr MAY ooNcEnN' l -Bevit'known tht we, BLIND. J osnIN, M. D.,and RUBEN A.NE WHALL, of North Brow'nville, inthe county of Kent, undState of'Mi'chig'hn, have invented e. new and useful Improvement inSpring- Bed Bottoms; and wedo declare that the following is a. truenndaccurete description thereof, reference being had to the accompanying(lm wings, and-tothe letters of reference marked tbereomnnd forming npart of thisspecitiation.

Figure-lise perspective vievi of our invention attached to a. bc'dstead:Figure 2 is a viewfofthe samc'uuattnchei nnd'showing the methodV of'construction. The same .letters indicate lilrepzirtsinV each igure. I iIt is a. Vwell-known fact that all bed-bottoms, which are, in part,-constructed of slats or strips ofwood, after I being used for some time,become depressed in the' centre, by thevbendngfof the slats from theweight imposed on them, and require tofbe renewed from time to time.v

The nature of this invention consistsrin so arranging a truss, a;ndo'ne'or'more'coil or 4othersprings between the slut and truss, as toprevent thistendeney'ot the slat to dedect in the centre; i

In order to accomplish this object we construct a sla-t, C, inthe.ordinary form, to run longitudinally, with reference to the side rails,B, ofthe bedstead. To this slat We a-ttachthe truss D, made fast' andturnedoverv the'ends of theslat, in such a, manner as to form a. loop,I, thtcnglrwhich is prnssed'the loop of the double coilspring`E,`whi'chspring encloss the rod or round bar B, and is attached to'the heed 'andfoot-miL'A, of tlie bedstead by meansof a proper loop in the centre ofthe4 doubleooil-springnnd the hook-J.A To the upper side of the truss'we attach coil or' other springs, `3, as mamy-as we deem best, whichsupport and prevent too' much d'eliecticn ofthe slet. v

l l.By using lour truss and vsupporting-springs, theslats may beattached to the 'hea'd and footernils of a. bedstea'fd by any otherwell-known device.

4What we .elniiu as our invention, and desire to secure by LettersPatent, vis--. n `1. The truss D, provided with supporting-springs 3,when cttached to slat C, und. opel-'ating substantially as ondfor thepurposes described. l

2g The combination of the trussed slats C with the'l rod B and hooks vJ,upon thedouble coil-spring E, for the purpose described. i
